It was a stillborn project from the get go. My first encounter with it was back in 97 in Paris /some mock ups/. Even back then many experts predicted the end of 4 engine airliners.
So much false information over the years, freighters, short-haul versions, blah blah...
If it wasn't for Emirates, it would've been long gone.
Pilots love to fly it, or at least that is what I've heard, but still, everybody I know who work in the area think that it was meant to prove a point more than to be actual achievement.
